If both Pipelayer and https://mods.factorio.com/mod/EditorExtensions is loaded, and you try to make a new blueprint that contains an Editor Extensions super pump, the game crashes with this message.
The mod Editor Extensions (1.13.1) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event EditorExtensions::on_player_setup_blueprint (ID 70)
__EditorExtensions__/scripts/entity/super-pump.lua:253: attempt to index local 'entity' (a nil value)
stack traceback:
__EditorExtensions__/scripts/entity/super-pump.lua:253: in function 'setup_blueprint'

In addition, if you try to make a blueprint of an Editor Extensions infinity pipe, the infinity pipe is ignored, doesn't get into the blueprint. Neither of these happens without Pipelayer.
